Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a hair restoration .

[0002]

2. Description of the Related Art Many steroid hormones are expressed in a molecular form secreted from a producing organ and bind to a receptor to exert their action. In the case of a male hormone collectively called androgen, for example, testosterone is a cell in a target organ. Once inside, it is reduced to 5α-dihydrotestosterone (5α-DHT) by testosterone 5α-reductase and then binds to a receptor to exert its action as an androgen.

[0003] While androgens are important hormones, their excessive action can lead to a variety of undesirable symptoms such as male pattern baldness, hirsutism, seborrhea, acne, prostatic hypertrophy, prostate tumors, precocious boyhood, etc. Trigger. Therefore, it is conceivable to improve these undesirable symptoms by suppressing the action of excessive androgen. Two methods can be considered as the means. One is to inhibit the activity of testosterone 5α-reductase, which reduces testosterone to 5α-DHT, thereby increasing the activity of 5α-reductase.
The other is a method of suppressing the occurrence of DHT, and the other is a method of inhibiting the binding of 5α-DHT generated from testosterone to a receptor so as not to exert an androgen action.

[0004] In these methods, many crude drug extracts are known to be effective.

For example, testosterone 5α-reductase inhibitors described in Japanese Patent Application Laid-Open No. Sho 60-146829 include Asenyaku, Fennel, Licorice, Kengoshi, Gobishi, Peony, Shazenshi, Senso, Daisou, Clove, Betelou, Rosin, The extract contains as an active ingredient an extract of cuckoo thistle, gennoshoko, kagosou, psycho, intin, age, yokuninin, soybean, nigaki, gayai, catalpa, japonicus, valerian.

[0006]

It is an object of the present invention to find novel plant extracts having an inhibitory effect on testosterone 5α-reductase, which can be used as testosterone 5α-reductase inhibitors and the above-mentioned undesirable symptoms caused by excess androgen. To provide a new means for the treatment of

DESCRIPTION OF THE PREFERRED EMBODIMENTS Gardenia (Gardenia j)
(Aminoides) is a plant of the family Rubiaceae, the fruit of which has been used as a Chinese herbal prescription drug for purposes such as antipyretic, anti-inflammatory and hemostatic.

[0012] Kujin (Sophora flavesc)
ens) is a leguminous plant, the roots of which have been used as diuretic and astringent lagoon medicines. In cosmetics, it has been used as an antibacterial agent.

[0013] Isodon japonicu
s) is a member of the Labiatae family and is also known as Hikikoshi. The whole plant has been used as a bitter stomach and as an antibacterial in cosmetics.

The fruits of gardenia, roots of jinjin and whole life-prolonging grasses are appropriately pulverized and then subjected to extraction using water, a hydrophilic organic solvent or a mixture thereof as a solvent. As the organic solvent for extraction, lower alcohols such as methanol and ethanol, and polyhydric alcohols such as 1,3-butylene glycol are most suitable. Although there is no particular limitation on the extraction method, the active ingredient can be easily extracted by immersion in a solvent maintained at room temperature or near the boiling point.

The hair nourishing composition according to the present invention, when mixed at a ratio of 20 to 40% of a gardenia extract, 30 to 60% of a jinjin extract, and 20 to 40% of a prolonged life grass extract, is more effective than when each is used alone. Is also highly effective.

The obtained extract is used alone or with an appropriate auxiliary in the form of a dermatological agent, an oral agent, an injection, a suppository, etc., according to a conventional method for preparing a plant extract of this kind. Formulate. As the dosage form of the external preparation, any dosage form such as tonic, rinse, lotion, cream, milky lotion, pack, ointment, bath preparation, etc. is possible, and as the internal preparation, tablet, capsule, powder, liquid, etc. Is possible.

In the case where the hair nourishes according to the present invention are used for cosmetics, it is preferable to use the cosmetics alone to make cosmetics.
Astringents, bactericidal / antibacterial agents, whitening agents, ultraviolet absorbers, humectants,
It can be used as a more general cosmetic if it is appropriately combined with other physiologically active substances and other active substances that can be used as cosmetic components such as cell activators, anti-inflammatory and anti-allergic agents, and antioxidants and active oxygen scavengers. It is possible to do. In such a case, a synergistic effect with another active ingredient used in combination may bring about an excellent use effect that is higher than the effect normally expected.

【Example】

[0038]

Test Example 1 (Testosterone 5α-reductase inhibitory action) 4.2 mg of testosterone (Tokyo Kasei) was dissolved in 1 ml of propylene glycol, and 20 μl of the solution was added to the solution.
DPH (manufactured by Oriental Yeast) at a concentration of 1 mg / ml
5 mM Tris-HCl buffer (pH
7.2) Add 825 μl and mix. Further, 80 μl of an ethanol solution of the sample and 75 μl of S-9 (rat liver homogenate; manufactured by Oriental Yeast Co., Ltd.) were mixed and mixed.
Incubate at 7 ° C for 30 minutes. Thereafter, 1 ml of methylene chloride is added to stop the reaction, the methylene chloride layer is separated, and dihydroxytestosterone, androstanediol and the like as reaction products are quantified by gas chromatography.

Separately, as a control, when the same amount of the solvent alone is added instead of the sample solution, the same treatment and analysis are performed. The ratio of the amount of the reaction product at the time of addition of the sample to the amount of the reaction product at the time of no addition of the sample is determined and defined as the testosterone 5α-reductase inhibition rate.

In the above method, the testosterone 5α-reductase inhibition rate at each concentration was determined by variously changing the sample concentration in the reaction solution, and the results were interpolated by interpolation.
The sample concentration IC ₅₀ that inhibits the enzyme activity by 50% is determined.

Twice a day, morning and night, the hair tonic was used instead of the usual hair tonic. In the non-use group, the hair tonic prepared in Example 1 except for the gardenia, jinn, and the life-extending grass extract was used in place of the commonly used hair tonic under the same conditions. Everyone was allowed to wash their hair under the same conditions on the test start date and test end date, and the number of hair removals at that time was counted.

In order to adjust the conditions, the hair was washed under the same conditions 24 hours before the hair washing for measuring the number of hair removal.
